nasapower aims to make it quick and easy to automate downloading NASA-POWER global meteorology, surface solar energy and climatology data in your R session as a tidy data frame tibble object for analysis and use in modelling or other purposes. POWER (Prediction Of Worldwide Energy Resource) data are freely available for download at a resolution of 1/2 arc degree longitude by 1/2 arc degree latitude.

nasapower offers further functionality to quickly and easily generate an APSIM package metFile format text file from POWER data for use in the Agricultural Production Systems sIMulator (APSIM) or an ICASA format text files for use in Decision Support System for Agrotechnology Transfer (DSSAT).

Please see https://power.larc.nasa.gov/ for more on the data and other ways to access it and other forms of data available, e.g., your web browser or an ESRI REST API.
